Spectacular San Francisco footage in UltraHD

Outdoor production company Teton Gravity Research (TGR) has assembled halting footage of San Francisco, from the Bay Bridge to the Golden Gate, engulfed in fog, to Market Street and the crashing waves of the coast.

And all of it is whirring on your screen in “UltraHD” or 4K, a format that requires a minimum resolution of 3,840 × 2,160 pixels. TGR has employed a new RED Epic-equipped gyrostabilized camera platform called the GSS C520.

RED makes a bevvy of super-powered video cameras that are increasingly affordable for Joe Filmmaker (which TGR is not). In November CEO Jim Jannard (who also founded sunglass-maker Oakley) announced huge price cuts across the board. Though the cameras are still a pretty penny, a 45 percent price cut will certainly bring some into budget range — especially since amateur filmmakers usually rent the devices rather than purchase them outright.
